Source SDK 2013 community repos

The Source modding community has stepped up to maintain various repositories that include Valve's SDK code plus community changes. You can find a list of some of the options for getting the source code from the community below.

• Nbc66/source-sdk-2013-ce - Nbc66 & Ian B.'s repo contains the SDK 2013 source with bug fixes and optional enhancements + experimental additions, also includes support for the v142 toolset which gives ability to compile with vs2019 eliminating the need for vs2013 to be needed to be used.
• Mapbase improves the engine and entities to be more capable and stable for mapping and other kinds of modding without changing too much of the game itself. It's designed to be used as a platform for mappers to build their maps on and for larger mods to draw code from. Mapbase is generally used as a massive package of utility features and general-purpose fixes.
